But Jayne says in observing more than PVC Screen reduces debris 10 sites so far, these installations offer a lot of variable control. entering pump “We measure what the nitrate concentration is in the outlet, and ideally if things are working properly, what we see is decreasing nitrate concentration as we go through our distribution pipe into the stream,” he explains. “In some  YOUR SOURCE for Complete Pump Station Solutions buffers, it happens quickly within the first 10 feet or so, and  Plug & Go Systems for a wide variety of applications all the nitrate is gone.

He knows that isn’t always going to be the case, but he’s pretty excited to see those results are achievable on his farm. “I’ve done both the bioreactor with woodchips and 2017-04-11 I’ve installed three saturated buffers now,” he says. “The DC_CarryPumps_May17_CSA.indd 1 saturated buffer is a third of the cost, the time to install it is so much quicker, and the research shows that we’re getting better nitrogen removal.” Typically, full installation takes about half-a-day and most of that time will be spent finding the outlet in the buffer if it’s not obvious. Once the new control box is in place, laying the new distribution pipe takes only a matter of minutes. Recker says that as farmers push for earlier planting seasons and work later into the fall, tiling work, which can be primarily done outside of a shrinking tile installation season, is good for landowners and tile drainage contractors alike. “These kind of jobs, they’re not difficult jobs,” he says. “If we can find a practice that we can be working all summer ”Palletized filter socks available for self installers” long, and it has the benefits of nitrogen removal – hey, that’s a win-win for everybody.” DC 1:29 PM NOVEMBER 2017 | DRAINAGE CONTRACTOR 31 DC_Etube_FilterSock_May17_CSA.indd 1 2017-04-18 11:08 AM
